The polymeric surface repairer and protectant composition may include a thinner component and a protective component. The polymeric surface repairer and protectant composition may further include an oil component. As an alternative to or in addition to the oil component, the polymeric surface repairer and protectant composition may include a drying component.

FIELD OF INVENTION

The present disclosure relates generally to compositions for improving the appearance of polymeric surfaces, more particularly to polymeric surface repairer and protectant compositions that clean, repair, recolor, and/or reseal polymeric surfaces to provide long lasting shine, coloring, and protection, methods for making the compositions, and methods of use for the compositions.

BACKGROUND

Polymeric surfaces that are used in applications in which they are exposed to the environment (e.g., heat, cold, sun, dirt, debris, chemicals, debris, etc.) tend to fade or wear out over time. One exemplary application in which this occurs is in the automotive industry. Conventional products to improve the appearance of faded automotive polymeric surfaces are generally provided as liquids which are sprayed or otherwise applied onto the surface to be treated. However, conventional products, and the improved appearance they may provide, wear away after only a short period of time. There is a need in the market for a product that provides a long-lasting, improved appearance to automotive polymeric surfaces.

DETAILED DESCRIPTION

In the description that follows, features that are described with respect to one embodiment may be used in the same way or in a similar way in one or more other embodiments and/or in combination with or instead of the features of the other embodiments.

The present disclosure provides a polymeric surface repairer and protectant composition for restoring faded and worn polymeric surfaces. In contrast with conventional polymeric surface restoration products that may simply coat a faded/worn polymeric surface, the polymeric surface repairer and protectant composition of the present disclosure may etch the polymeric surface so that one or more of the components of the composition may bind thereto and/or become impregnated therein. As used herein, the term “surface” refers to the outermost part of the polymeric material to include cracks, crevices, and crazing, and any newly revealed portions of the polymeric material exposed by etching. As used herein, the term “etch” or “etching” refers to melting the polymeric surface, creating minute cracks (i.e., crazing) on the polymeric surface, dissolving the polymeric surface such that the polymeric surface dissolves into the applied composition, a chemical reaction with the polymeric surface, or a combination thereof. Additionally, the polymeric surface repairer and protectant composition of the present disclosure may provide superior performance in multiple climate conditions (e.g., driving rain, snow, extreme ultraviolet radiation, extreme heat and cold, extreme humidity and dryness). The polymeric surface repairer and protectant composition may thereby provide long lasting shine, coloring, and protection. Unlike conventional restoration products, since the composition of the present disclosure maintains a restored polymeric surface finish for an extended period of time (e.g., two months to one year), the composition may not require monthly re-applications. Moreover, the polymeric surface repairer and protectant composition may be non-destructive such that any flaws may be fixed with a re-application on top of the previous application. This property allows for the polymeric surface to be usable after an application and re-application of the disclosed composition may again yield a restored polymeric surface.

As described below, the polymeric surface repairer and protectant composition may be applied to a polymeric surface and allowed to dry for a period of time. One exemplary embodiment of a polymeric surface to which the polymeric surface repairer and protectant composition is applied is a polymeric surface used in an automotive application (e.g., automotive plastic). It will be appreciated that while the polymeric surface repairer and protectant composition of the present disclosure may have particular application to automotive polymeric surfaces (e.g., trim and/or light cover) repair and protection, the principles of the disclosure may be useful for any polymeric surface application where it is desirable to provide polymeric surface repair and protection.

The polymeric surface repairer and protectant composition of the present disclosure includes at least one thinner component and at least one protective component. The at least one thinner component may clean, etch the polymeric surface, and may alter or set drying time of the polymeric surface repairer and protectant composition. The at least one protective component may provide protection and a desired surface finish to the polymeric surface. In some embodiments, the polymeric surface repairer and protectant composition may further include at least one oil component. The at least one oil component may provide a desired sheen to the polymeric surface. In some embodiments, as an alternative to or in addition to the oil component, the polymeric surface repairer and protectant composition may include at least one drying component. The at least one drying component may alter drying time of the repair and protectant composition.

In some embodiments, the at least one thinner component may include acetates (e.g., ethyl acetate, methyl acetate, n-propyl acetate, n-butyl acetate, t-butyl acetate), esters (e.g., dimethyl carbonate), ethers (e.g., glycol), alcohols (e.g., butanol, propanol), ketones (e.g., methyl ethyl ketone, methyl isobutyl ketone, acetone), hydrocarbons (e.g., mineral spirits, turpentine, naphtha, petroleum naphtha, benzene, ethylbenzene, trimethyl benzene, cumene, toluene, xylene, kerosene, diesel fuel, petroleum), amides (e.g., dimethylformamide) or a mixture of two or more thereof. In some embodiments, the at least one thinner component may include polar aprotic solvents (e.g., acetone, ethyl acetate, methyl ethyl ketone), non-polar aprotic solvents (e.g., benzene, cumene, naphtha, trimethyl benzene, xylene isomers), or a mixture thereof. In one example, the at least one thinner component includes naphtha, xylene, and methyl ethyl ketone. In one example, the at least one thinner component is a paint thinner. An exemplary paint thinner is available from Klean-Strip® (Memphis, Tenn.) as Klean-Strip® Paint Thinner. The at least one thinner component may clean the polymeric surface to which the polymeric surface repairer and protectant composition is applied. The at least one thinner component may also etch the top layer of polymeric surface to which the polymeric surface repairer and protectant composition is applied, thereby creating minute cracks which are then impregnated by another component of the composition (e.g., the at least one protective component). This etching may occur as a result of a reaction between the polymeric surface and the at least one thinner component. Subsequent to etching, the at least one thinner component may alter or set drying time properties. For example, a higher amount of the at least one thinner component may shorten drying time, which may be a desired feature in an automotive polymeric surface application (e.g., allows for returning a car to a customer more quickly). The at least one thinner component may also even out the surface finish of the polymeric surface repairer and protectant composition. The at least one thinner component may be present in any suitable amount. In one example, the at least one thinner component may be present in the polymeric surface repairer and protectant composition from 1% to 75% by volume of the polymeric surface repairer and protectant composition, or in another example, 1% to 50% by volume of the polymeric surface repairer and protectant composition, or in another example, 1% to 25% by volume of the polymeric surface repairer and protectant composition, or in another example, 1% to 10% by volume of the polymeric surface repairer and protectant composition, or in another example, 1% to 5% by volume of the polymeric surface repairer and protectant composition, or in another example, 10% to 75% by volume of the polymeric surface repairer and protectant composition, or in another example, 25% to 75% by volume of the polymeric surface repairer and protectant composition, or in another example, 50% to 75% by volume of the polymeric surface repairer and protectant composition, or in another example, 10% to 25% by volume of the polymeric surface repairer and protectant composition, or in another example, 10% to 50% by volume of the polymeric surface repairer and protectant composition, or in another example, 10% to 55% by volume of the polymeric surface repairer and protectant composition, or in another example, 25% to 50% by volume of the polymeric surface repairer and protectant composition, or in another example, 35% to 55% by volume of the polymeric surface repairer and protectant composition, or in another example, 40% to 50% by volume of the polymeric surface repairer and protectant composition.

In a preferred embodiment, the dispersant component is present in the polymeric surface repairer and protectant composition in 25% by volume of the polymeric surface repairer and protectant composition.

In some embodiments, the polymeric surface repairer and protectant composition may include at least one surfactant component. The at least one surfactant component may include, but is not limited to, a non-ionic amphiphilic surfactant such as ethoxylated alcohols (e.g., decanol ethoxylate or lauryl alcohol ethoxylate), alkyl phenols (e.g., p-decylphenol, p-dodecylphenol), commercial surfactants, or any mixture thereof. Surfactant components are available, for example, as Triton™ X-100 and IGEPAL® CA-630. In some embodiments, the at least one surfactant component may be used to adjust the surface tension or one or more other physical properties of the repairer and protectant composition so that the composition can be used in a suitable application. In some embodiments, the at least one surfactant component may promote mixing of the components of the repairer and protectant composition. In one example, the at least one surfactant component may be present in the polymeric surface repairer and protectant composition from 0% to 10% by weight of the polymeric surface repairer and protectant composition, or in another example, 0.1% to 10% by weight of the polymeric surface repairer and protectant composition, or in another example, 0.1% to 5% by weight of the polymeric surface repairer and protectant composition, or in another example, 0.1% to 1% by weight of the polymeric surface repairer and protectant composition, or in another example, 0.5% to 10% by weight of the polymeric surface repairer and protectant composition, or in another example, 0.5% to 5% by weight of the polymeric surface repairer and protectant composition, or in another example, 0.5% to 5% by weight of the polymeric surface repairer and protectant composition, or in another example, 1% to 10% by weight of the polymeric surface repairer and protectant composition, or in another example, 1% to 5% by weight of the polymeric surface repairer and protectant composition.

The polymeric surface repairer and protectant composition of the present disclosure may be formulated to clean, repair, recolor, and reseal polymeric surfaces. The polymeric surface repairer and protectant composition may provide long lasting shine, coloring, and protection. In some embodiments, dirt or debris may be removed from the polymeric surface upon application of the polymeric surface repairer and protectant composition. Accordingly, this may eliminate the extra step of cleaning the polymeric surface generally required before applying a conventional composition. Once applied to the polymeric surface, the polymeric surface repairer and protectant composition may react with the polymeric surface to etch the polymeric surface. This etching may be caused by the thinner component of the polymeric surface repairer and protectant composition. Upon etching, other components (e.g., the protective component and one or more of the other components such as the at least one coloring component) may become embedded therein to the polymeric surface and any newly formed voids in the surface. During a period of time (e.g. drying period), the thinner component and other components (e.g., the at least one drying component) may be removed via drying. Any remaining components, including components that were dissolved in the composition, may adhere (e.g., bind, become intimately coated, become impregnated) to the etched surface, dry to solid form, and become embedded therein. The polymeric surface may reset (e.g. reseal, reharden or assume a solidified form) and may encapsulate the polymeric surface repairer and protectant composition and any dissolved components of the polymeric surface.

The adherence and embedding of the polymeric surface repairer and protectant composition to the polymeric surface may lead to durability (e.g., prevent flaking) and may provide a long-lasting gloss and/or shine to the polymeric surface. The thermal expansion and contraction of the polymeric surface repairer and protectant composition may be similar to or equal to the thermal expansion and contraction of the polymeric surface, which may lead to durability and prevent shearing of the polymeric surface. In other embodiments, the polymeric surface may require pretreatment (e.g., cleaning) before application of the polymeric surface repairer and protectant composition such that the polymeric surface repairer and protectant composition repairs, recolors, and reseals polymeric surfaces. In other embodiments, the polymeric surface repairer and protectant composition may be formulated to repair and reseal polymeric surfaces.

As used herein, the term “drying period” refers to the time in which the polymeric surface dries to the touch. In one example, the drying period may be in the range of 15 seconds to 24 hours, or in another example, 1 minute to 24 hours, or in another example, 1 minute to 12 hours, or in another example, 1 minute to 6 hours, or in another example, 1 minute to 3 hours, or in another example 1 minute to 1 hour, or in another example, 15 seconds to 30 minutes. The polymeric surface may fully cure (e.g., curing period) after the drying period. In one example, the curing period may be in the range of 12 hours to 7 days, or in another example, 12 hours to 3 days, or in another example, 12 hours to 24 hours.

The polymeric surface repairer and protectant composition may be applied to the polymeric surface to be treated in a number of ways, such as pouring the polymeric surface repairer and protectant composition directly onto the polymeric surface; applying the polymeric surface repairer and protectant composition to a cloth, pad, sponge, scrub, foam brush, or the like and then using such on the polymeric surface; or pre-loading the polymeric surface repairer and protectant composition on a wipe and using the pre-loaded wipe on the polymeric surface. The polymeric surface repairer and protectant composition may be in the form of a liquid, gel, paste, or spray. The particular form of the polymeric surface repairer and protectant composition may depend, for example, on the particular dispersant(s) used in the composition, as well as the types and amounts of the other components utilized in the composition.

In some embodiments, the polymeric surface repairer and protectant composition may be applied to polymeric surfaces such as plastics including polypropylene (PP), high density polyethylene (HDPE), polyvinyl chloride (PVC), low density polyethylene (LDPE), polyurethane, polystyrene, acrylonitrile butadiene styrene (ABS resin), polybutylene terephthalate (PBT), polyoxymethylene (POM), nylon, polyethylene terephthalate (PET), polycarbonate (PC), polyesters, or a mixture of two or more thereof. In some embodiments, the polymeric surface repairer and protectant composition may primarily adhere to polymeric surfaces, not clear coats and paints. Accordingly, if the polymeric surface repairer and protectant composition is accidentally applied to the paint of a car while applying the protect composition to the automotive trim, the polymeric surface repairer and protectant composition may be easily removed from the paint. The prevention of adherence to coats and paints may be controlled by the amount of the at least one thinner component in the polymeric surface repairer and protectant composition. For example, the at least one thinner component may alter drying time of the polymeric surface repairer and protectant composition. Accordingly, a lower amount of thinner component may lengthen drying time so that the polymeric surface repairer and protectant composition may be removed from the paint before it dries.

In addition to being applicable to automotive trim (e.g., bumper), the polymeric surface repairer and protectant composition may be applied to automotive transparent polymeric surfaces (e.g., headlights and taillights). The polymeric surface repairer and protectant composition may restore a faded transparent polymeric surface back to partial or full transparency. In some embodiments, the restored polymeric surface has a similar refractive index as transparent polymeric surfaces (e.g., headlights and taillights) and permits a light to transmit through the surface in a pattern similar to the original polymeric surface (e.g., after manufacturing of headlight or taillight). The polymeric surface repairer and protectant composition may also fix scaring or scratches of the transparent polymeric surface to improve transparency by etching the polymeric surface such that the composition is embedded in the scaring or scratches. The polymeric surface repairer and protectant composition may remove the appearance of such scratches. Conventional products require wet sanding after application to a transparent polymeric surface, which necessitates protective gear and more time than the application of the repairer and protectant composition of the present disclosure. By contrast, in some embodiments, the polymeric surface repairer and protectant composition of the present disclosure may be applied and allowed to dry without the need for any further steps.

In some embodiments, the polymeric surface repairer and protectant composition may be formulated to be safely applied without emitting any odors, fumes, vapors or toxins such that venting is not required. The polymeric surface repairer and protectant composition may be formulated to be free of volatile organic compounds and harmful chemical secretions such that safety apparel (e.g., gloves) is not required during application of the polymeric surface repairer and protectant composition.

In some embodiments, the process for making the polymeric surface repairer and protectant composition may include at least one mixing step. In one example, the at least one thinner component and the at least one protective component may be mixed to produce the repairer and protectant composition. In some embodiments, the process for making the polymeric surface repairer and protectant composition may include combining a first mixture including one or more components with a second mixture including one or more components to yield the polymeric surface repairer and protectant composition. In one example, the at least one thinner component is mixed with an oil component to form a first mixture, the at least one protective component and at least one coloring component are mixed to form a second mixture, and the first and second mixture are mixed to yield the polymeric surface repairer and protectant composition. In some embodiments, the process for making the polymeric surface repairer and protectant composition may include a step-wise addition of separate components. In one example, the at least one thinner component is mixed with the protective component to form a first mixture, the first mixture is mixed with a drying component to form a second mixture, and the second mixture is mixed with a coloring component to yield the polymeric surface repairer and protectant composition.
